The ball mill treatment reduced chromite grains greater than 15.77 µm down to sizes less than 11.15 µm in diameter, and thus released chromite-bound Cr(VI) for sulfide reduction. Magnesioferrite encapsulated Cr(VI) was released and reduced similarly with grain size change from 15.77 to 37.5 µm to below 15.77 µm.
They were hand-picked to remove any visible impurities after crushing. The samples were dry-milled using a porcelain ball mill and sieved to obtain a particle size of −0.074 + 0.038 mm, placed in a brown wide-mouth bottle, and stored in a refrigerator for flotation. Detailed descriptions of the mineral samples are presented in Table 1. The ...
